On silent snowy nights, when no sounds can be heard, many people go deaf in one or both ears. The doctors can't do anything, so they think it might be paranormal. Ginko looks into some of the villager's ears and he tells them that the cause is a Mushi called "Un". After dealing with their small problems there is one more person who has lost sound in both of his ears and his condition is very different than the other people's, as he has also grown four horns on his head.
